Abstract
The invention discloses precision water system scale removers, which comprise, by weight, 13.3-16.8% of nicotinic acid, 8.0-10.3% of glacial acetic acid, 6.6-9.1% of ammonium bifluoride, 1.8-2.8% of sodium gluconate and the balance of water.
Description
Technical Field
The invention belongs to the technical field of water treatment, and particularly relates to precision water system scale remover and a preparation method thereof.
Background
After the water cannot be boiled in daily life, equipment of a plurality of factories, restaurants and hotels also needs water, such as various common precision water systems of heat exchangers, cooling water towers, air conditioners, condensers and the like, after periods of operation and use, because impurities and microorganisms in the water are heated and deposited and adsorbed on heat exchange surfaces, the deposits are called scale, the composition of the scale is complex and generally consists of substances such as compounds, algae, silt and the like, after the scale is generated, the heat exchange efficiency of the equipment is reduced, and statistically, when the thickness of the scale reaches 0.1mm in the precision water systems of , the heat efficiency is reduced by about 5 percent, so the normal use of the equipment is directly influenced after the scale is generated, therefore, a plurality of methods are adopted to remove the scale, the manual scale removal is , but the manual scale removal is ineffective for the equipment with complex shape, while the chemical cleaning method of , which adopts common chemical cleaning agents, can remove the scale, needs professional knowledge, severely corrodes the equipment with thinner walls, and the is necessary for research and development of precision water systems.
Chinese patent CN 201010100925.5 discloses high-efficiency cooling system cleaning agents with spectrums, which comprise, by mass, 1-5% of organic acid, 0.5-3% of metal ion chelating agents, 0.5-2% of cleaning accelerators, 0.1-1% of corrosion and scale inhibition dispersing agents, 0.3-5% of degreasing agents and the balance of water, wherein the cleaning agents are safe to use, the cleaning time is 1-2 hours, the descaling rate is more than 90%, corrosion damage to a cooling system is greatly reduced, the organic acid is or two mixtures of sulfamic acid, citric acid, glycolic acid, oxalic acid and tartaric acid, the chelating agents are mixtures of ethylenediamine tetraacetic acid and diethylenetriaminepentaacetic acid, the cleaning accelerators are or two mixtures of ammonium bifluoride, sodium fluoride and potassium fluoride, and the corrosion and scale inhibition dispersing agents are composed of sodium gluconate, acrylic acid-methyl acrylate and styrene sulfonic acid-maleic anhydride.

The second object of the present invention is to provide a method for preparing the above-mentioned scale remover for precision water system.
The descaling agent for the precision water system comprises the following components in percentage by weight:
the scale remover for the precision water system can also be added with 5.6 to 7.6 percent of hydrogen peroxide, and the concentration is 25 percent.
The precise water system scale remover is prepared from the following components in percentage by weight:
the invention utilizes hydrogen ions provided by glacial acetic acid and nicotinic acid to remove scale, ammonium bifluoride provides fluoride ions, and the sodium gluconate belongs to the effects of corrosion inhibitors and complexing agents and has strong permeability.
The invention discloses a preparation method of a precise water system scale remover, which comprises the following steps: weighing the components, blending, stirring and dissolving uniformly.
The application method of the precision water system scale remover comprises the following steps: and soaking the equipment to be descaled in the descaler of the precision water system, taking out the equipment after the dirt completely falls off, and washing the equipment by using clear water.
The descaling agent for the precision water system has the following beneficial effects: the scale removing agent does not corrode equipment, has no odor, has the scale removing rate of more than 96 percent, does not corrode a human body, and has high scale removing speed.
Detailed Description
The invention is further illustrated by examples which are not intended to be limiting.
Table 1 shows the formulations of examples 1 to 4 and comparative examples 1 to 2 in wt%.
